Abstract
Description
原料リチウム−マンガン−ニッケル−コバルト酸化物(LMNC)材料を製造すること、
要すれば、LMNC材料の製造時に、電気化学セル中の陽極材料として使用するときに層状LMNC材料の性能を向上し得るドーパントを導入すること、
原料LMNC材料のアニールを行う前に、前記材料をマイクロ波処理して処理材料を得ること、および
処理材料をアニールして層状LMNC材料を得ること、
を包含する、層状リチウム−マンガン−ニッケル−コバルト酸化物材料の製造方法を提供する。
溶解リチウム化合物、溶解マンガン化合物、溶解ニッケル化合物、溶解コバルト化合物、要すれば溶解ドーパント化合物、ヒドロキシカルボン酸およびポリヒドロキシアルコールを含有する溶液を、溶液の沸点より低い高温度T1で、溶液がゲル化するまで保持すること、
前記ゲルを、発火または燃焼してLi−Mn−Ni−Co−O粉末を形成するまで高温度に保持すること、および
前記Li−Mn−Ni−Co−O粉末を焼成して前記粉末中に存在する炭素および/または他の不純物を焼き抜きして、それにより原料層状LMNC材料を得ること
によって行ってもよい。
親Li[Li0.2Mn0.54Ni0.13Co0.13]O2(LMNC)およびAlドープLi[Li0.2Mn0.52Ni0.13Co0.13Al0.02]O2(LMNCA)を、変形1段階粉末形成ペチニ法を用いて調製した。クエン酸(CA)、エチレングリコール(EG)および硝酸金属(Li、Ni、Co、Al)を出発材料として使用した。還元剤、CA(脱イオン水に溶解)およびEGを1:4(CA:EG)のモル比で混合し、約90℃で加熱し、その間10分間連続的に撹拌した。LiNO3、Ni(NO3)2.6H2O、Co(NO3)2.6H2O、Mn(NO3)2.4H2OおよびLMNCAについてAlN3O9.9H2Oの化学量論量を脱イオン水に溶解して、CAおよびEGを含有する還元溶液中に滴下導入した。各溶液およびサンプルを脱水してゲル中にした。溶液が自然に所望の粉末を形成するまで、ゲルを90℃に保持した。粉末(LMNCおよびLMNCA)を、500℃で6時間予備加熱し、各々二つのバッチに分けた。その一つのバッチを700℃で8時間アニールし、その際温度を10℃/分の割合で加熱し、次いで室温にまで自然冷却した。尚、冷却時、フィラメントへの電力供給を8時間後に停止し、得られたサンプルを各々LMNCおよびLMNCAとした。もう一方の半分を、マイクロ波(λ=0.12236m)に照射し、その際電力を60W/分の割合で600Wまで増加し、600Wで15分間照射し(サンプルの温度は最大60℃に到達した)、次いで700℃で8時間アニールした。その際温度は10℃/分の割合で増加し、次いで室温まで自然冷却した。尚、冷却時、フィラメントへの電力供給を8時間後に停止し、得られたサンプルを各々LMNC−micおよびLMNCA−micとした。
図1は、LMNC−micおよびLMNCA−micのSEM画像の比較を示し、合成材料がLMNC−micでは250〜300nmの大きさであり、LMNCA−micでは100〜200nmの大きさを有するナノサイズの粒子から構成されることを反映している。これらの粒子の大きさは、マイクロ波処理をしていないサンプル(LMNCおよびLMNCA)のそれと同程度である。
